f(x) = g(x) will be the input or x value at which f and g have the same output or y value. Look in the table where two numbers repeat right next to each other.

−1 −7/2 −9/2

0 −3 −3

1 −2 −3/2

2 0 0

5 28 9/2

There are two solutions to f(x) = g(x) which are x=0 and x=2.

John, Paul, and George gather aluminum and tin cans to exchanges for money at the local recycling plant. One day, the three men

forsale [732]

To find the percent of the total that George collected, you need to create a ratio with the number of pounds George collected compared to the number of total pounds that were collected.

You will then divide these to find the part (decimal) that George collected. You can convert the decimal to a percent.

3 1/4+6 1/3+11 1/6 = 20 3/4 total pounds of cans.

11 1/6 George
20 3/4 total

11 1/6÷20 3/4 = 0.538
0.538 is approximately 54%.

George collected proximately 54% of the total amount of cans.

pls help for 15 points asap Phil traveled with his family by car. They started their trip from Lexington to Louisville, driving

victus00 [196]

Given that Phil traveled with his family by car. They started their trip from Lexington to Louisville, driving directly west for 60 miles.

So AB=60

They then turned North, driving to Indianapolis which is 100 miles from Lexington.

So AC=100

Then, they turned to the West again, and drove to Decatur which which is 170 straight miles from Louisville.

so BD=170

Now we have to find about how many miles did they cover in total driving from Lexington to Decatur.

That means we have to find length of (AB+BC+CD)

We can use Pythogorean theorem to find the values of BC and CD.

$BC=\sqrt{AC^2-AB^2}=\sqrt{100^2-60^2}=\sqrt{10000-3600}=\sqrt{6400}=80$

$CD=\sqrt{BD^2-BC^2}=\sqrt{170^2-80^2}=\sqrt{28900-6400}=\sqrt{22500}=150$

then (AB+BC+CD)=60+80+150= 290

Hence final answer is miles.
